27 August 2008, NB, Canada. Ovipositor of a Tachinid. Resembles Celatoria but neither of the 2 species in this genus get as far north as NB. EDIT: title changed Tony T attached the following image:  [124.6Kb] Edited by Tony T on 05-09-2008 10:30 |

It is clearly a Blondeliini, so point 119 in key by Wood (Manual). An obvious possibility is Compsilura: eyes are hairy and I don't see ocellar bristles. Facial ridge with strong bristles going up. That's one genus we share. Theo |

Yes, the piercer and the saw-toothed bristles where the tergites touch ventrally is quite distinctive of a few genera - should be easy to key out  |

Damn, now you are really putting me on the spot. At the moment I'm batting 100, I can't do better but if my ID is wrong I'll have mud on my face. So trust me, I know what it is. It's a European Compsilura and we have only 1 in NA. |

Compsilura concinnata. Interesting case. "Palaearctic. Introduced and established in northeastern USA and southeastern Canada, etc, etc" (Catalogue of the Tachinidae of America north of Mexico, O'Hara & Monty Wood, 2004) So that's why it looked so familiar ! Theo |

If it is Compsilura then they would look great in the gallery  |

The wing venation, hairy eyes, lack of ocellars and 4 post DC (unusual in Blondeliini): all indicates Compsilura concinnata. So there can be no doubt. Theo |

I'd say submit all of them - they all look great and any non-layered photos of Compsilura are unlikely to be better |
